Common Questions
Q1: When migrating from Datadog to Nightingale, do I need to switch the Agent?
A:
- You can keep it: let Datadog Agent send data to n9e (which is compatible with the Datadog API format);
- Switching to Categraf is recommended: lower long-term maintenance cost and better compatibility on the n9e side.
Q2: Can Datadog’s built-in alert rules be migrated to n9e?
A: They need to be rebuilt manually. Datadog uses its own query syntax (such as avg:system.load.1{*}), while n9e uses PromQL — they cannot be directly converted.
